摘要

Non-covalent interactions are one of the primary driving forces for constructing advanced functional materials. Using this strategy, the formation of advanced assemblies relies on multiple weak forces, rather than covalent bonds, to synergistically create complex, higher-order structures. The resulting assemblies often exhibit dynamic responsiveness, self-healing properties, and adaptability. When supramolecular structures incorporate fluorophores, the assembly processes frequently involve interactions that can lead to aggregation-induced quenching (ACQ). By integrating aggregation-induced emission (AIE) characteristics with supramolecular assembly, we can not only diversify the fluorescence properties of these assemblies but also track the self-assembly and disassembly processes in situ through the dynamic, real-time, and non-destructive features of fluorescence imaging. This encyclopedia focuses on advancing the design, synthesis, and application of high-performance supramolecular fluorescent materials with AIE properties, categorized by various supramolecular driving forces, including hydrogen bonding, host-guest interactions, metal coordination, π-π stacking, and electrostatic interactions. It discusses existing challenges and outlines future directions in the field, aiming to accelerate the practical application of supramolecular fluorescent materials.
